Nose
Massively bourbony; a roasty, slightly nutty-sweet, cocoa-dry aroma. Fascinating sub- strata of bamboo shoots and malt. Big and complex.
Palate
Aged from the off: very dry oaky tones and roast malt. Very chewy.
Finish
Sweetens drastically with toffee-vanilla and some fading coffee on the long, tapering finish.
Comment
An enormous whisky which hangs together impressively for its great age.

The famed Sazerac Coffee House was founded in 1850 at 13 Exchange Alley, New Orleans, Louisiana. Although styled a "Coffee House", it was, in fact, a saloon. The Sazerac Coffee House gained fame as the home of the Sazerac, "America's First Cocktail."

The family-owned Sazerac Company has since become the proud owner of the original Kentucky distillery that supplied that rye whiskey to the Sazerac Coffee Housee, and is, after a 110-year absence, pleased to bring you Sazerac 18 Year Old Rye Whiskey. Sazerac 18 Year Old Straight Rye Whiskey demonstrates a sophistication and style that is second to none. A hearty whiskey with a strong body, a mellow spice and a dry sweetness that dances on the tongue, it is the only 18 year old whiskey worthy of the Sazerac name.

Nose
Perfumed, lemon cooked fruits. Fairly lean with (in time) cocoa/coffee cake, winey notes. Whiff of cigar smoke as well.
Palate
Attractive if slightly (surprisingly) austere. The mid-palate has lovely concentrated jammy fruits alongside some good spicy rye.
Finish
Softens and begins to mellow.
Comment
Quite a mouthful which takes no prisoners
